GLAZING CLIP.

Application led January 12, 1927. Serial 11o. 160,695.

The object of this invention is to provide a simple and efficient glazing clip, especially for green houses, which can be manufactured at a low cost, being formed from strips of sheet metal by automatic machinery; and which when in use re laces the old method of securing the glass y nails in the green house roof, side walls, Ventilating frames, hot and cold outdoor frames, etc., and obviates the destruction of the glazing bars, common under the old method and which 1s well known to all users and builders ot the above named structures.

Referring to the drawings:

Fig. 1 is a transverse sectional elevation through a portion of a green house root and side wall Ventilating sash, illustrating a typical utilization of my invention;

F ig.'2 is a face view of the Ventilating sash;

Fig. 3 is a transverse sectional elevation of one ot' the root glazing strips, taken on the line 3-3 of Fig. 1;

Fig. 4 is a. sectional elevation taken on the line 4-4 of Fig. 3; and A Figs. 5 to 10 inclusive illustrate the various foi-ms ot' the clip, each constructed in a manner to meet the particular condition at hand.

Common to all green house construction is an eaves plate 1 which forms a support for the roof glazing bars 2 and to which the ventilating side wall frames `3 are usually pivoted.

The root glazing bars 2 are constructed in the manner illustrated in Fig. 3, being provided with shoulders 4, 4 upon which is successively placed a body of putty 5, on which the lights, or panes of glass, 6, 6 are laid, each upper light overlapping the underlying light as shown in Figs. 1 and 4. Intermediate the shoulders 4, 4 is a vertically extending tongue 7, which extends over the eaves plate 1 as shown at 7 a in Fig. 1.

My improved clip 10, illustrated in Fig. 5, is provided with top plate llhaving integral side plates 12, 12 thereon. Each side plate 12 is provided with a stepped foot which coinprises a lateral flano'e 13 adapted to engage the lowermost or underlying light 6, a second lateral flange 14 adapted to engage the top surface of the upper-light 6, at a top joint in the roof structure. The lower and upper lateral flanges 13 and 14 respectively are integrally connected by a web 15 which functions as a shoulder to engage the bottom edge of the upper light 6 and prevent it sliding down the incline of the roof, relative to the underlying light 6. A bridge rib 16 is formed 1n the top and side plates 11 and 12, 12 to stilen the clip. An aperture 17 is formed in the top plate 11 for the reception of a securing screw 18 which enters the vertical tongue 7 of the roof glazing bar 2.

lobviously, by tightening the screw 18, the clip l() is held securely to the bar 2, the foot flanges 13 and 14 bear on the light 6, 6 and prevent their being raised or loosened and the shoulder 15 engages the bottom edge of the upper light 6 and prevents relative longitudinal movement between the adjacent and overlapping lights. In replacing broken lights, it is necessary to remove only the one screw 18 at each corner of the light, which may be quickly and easily replaced, no nailing with its consequent destruction of the roof hars 2 being necessary.

Figs. 6 and 7 illustrate respectively the lap joint clip 10l and 10" employed at the right and left ends of the roof, their construction being identical with that of the clip 10, shown in Fig. 5, with the exception that in each instance one of the side plates 12 is removed.

Fig. 8- illustrates a clip 10C which is einployed on the bars 2 at the eaves plate 1. The top plate 11El in this instance is placed in advance of the lateral feet in order to place the screw opening 17a a suflicient distance from the end 7a of the tongue 7 of the bar 2, to prevent splitting of the said tongue when the screw 18 is put in place. In this instance one lateral foot flange is dispensed with as only one light is to be gripped. The 'oot flange 14c engages the top face of the single light 6 and the shoulder 15c engages the lower edge of said light to prevent it from slipping down the incline.

ln Fig. 2, I have illustrated a Ventilating side wall sash in which the top, bottom and side rails and intermediate rails 20, 21, 22 and 23 respectively are of equal thickness and shouldered below one face thereof to receive the lights 6d.

The form of clip 106 illustrated in Fig. 9 is employed at each corner of the trame 3 and consists of a top plate 11d, side plates 12d which adjoin each other at one edge and merge into a single foot plate 14d. At the points where the intermediate rails 23 join the top and bottom rails 20 and 21 respectively the clip 10e,\shown in Fig. 10, is employed and comprises a top plate 119,. side plates 12e and foot plates 14. The side and foot plates 12" 'and 14 extend to each side of the intermediate rail 23, as shown, and engage the face of the lights. At the lap of the lights 6d, the clips 10, 10a and l()b are employed as shown.

From the above description, it will be obvious that in each instance I have provided a lazing clip which eliminates the nail for lgiolding the glass Which is unsatisfactory and destructive when replacing lights. By the removal of a screw, which can be replaced in the same hole repeatedly, the destruction of the glass supporting structure and the inconvenience encountered when replacingbroken lights is eliminated.

I claim: 1. In combination with a glass supporting structure, a glazing clip comprising a top plate; a side plate integral with said top plate; a laterally extending integra-l flange' on said side plate; a second integral and laterall extending flange on said side plate in a di erent but p-arallel plane relative to said first flange; and a web integral With said side plate and both of said lateral flanges and connecting the said flanges ina manner to form a shoulder extending at right angles to the rcspective planes of said flanges.

2. In combination with a glass supporting structure, a glazing clip comprising a top plate; a side plate integral with said top plate and depending from each side of said top plates; a laterally extending integral flange on each of said side plates; a second integral and laterally extending flange on each of said side plates in a different but parallel plane relative to said first flange; and a web integral with each of said side vplates and both of said lateral flanges thereof and connecting the said flanges in a manner to form a shoulder extendingat right angles to the respective planes of said flanges.

3. In combination with a glass supporting structure, a glazing clip comprising a top plate; a side plate integral with said top plate and depending from each side of said top lplate; a laterally extending integral flange on each of said side plates; a second integral andlaterally extending flange on each of saidv side -plates in a different but parallel plane Leonesa relative to said first flange; a webV integral with each of said side plates and both of said lateral flanges thereof and connecting the said flanges in amanner to form a shoulder extending at right angles to the respective planes of said flanges; and a stifening rib formed on said top plate and each of said side plates.

4. In combination with a glass supporting structure, a glazing clip comprising a top plate; a sidel plate integral With said top plate `and depending from each side of said top plate; a laterally extending integral flange on each of said side plates; a second integral and laterall extending flange on each of said plates in a ifferent but parallel plane relative to said first flange; a web integral with each of said side plates and both of said lateral flanges thereof and connecting the said flanges in a manner to form a shoulder exture.

5. A glazing clip adapted to be pressed from a single piece of relatively thin sheet metal and comprising'a top plate; a side plate at each side of said top plate; a 'foot plate extending laterally from each of said side plates and having a longitudinal stepped formation comprising a pair of tread sections disposed at different but parallel planes and a riser section integrally connecting the said tread sections.

6. A glazing clip adapted to be pressed from a single piece of relatively thin sheet metal and comprising a top plate; a side plate at each side of said top plate; a foot plate extending laterally from each of said side plates and having a longitudinal stepped formation comprising a pair of tread sections disposed at different but parallel planes and a riser section integrally connecting the said tread sections; and a stiffening rib pressed in said rtop and side plates. v
